Sunday and Sunday Night …
Weather Hazards expected …
No weather hazards expected Sunday, but be prepared fog early Monday morning and gusty southeast winds during the day Monday. Winds will peak around midnight and continue into Tuesday morning. Also, melting snow with the resulting water on sidewalks and roadways could cause very slippery conditions when surface water freezes overnight Sunday to Monday from about 7:00 p.m. Sunday to 11:00 a.m. Monday.
DISCUSSION…
Southwest winds still gusting into the 30 mph range at times early this morning and these gusts will diminish some by daybreak as directions slowly turn more westerly later this morning and then northwest this afternoon. Gusts into the 25 mph range will remain possible through mid/late afternoon. High pressure will move across the area tonight with winds becoming light and variable or calm overnight Sunday/Monday.
Daily low temperatures and daily high temperatures are on the way up. We’re gaining about 2 minutes of daylight every day in the progression toward vernal equinox, March 20, 2023. Gaining three minutes of daylight on Sunday, February 5, 2023.

Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
522 AM CST Sun Feb 5 2023
.SHORT TERM… Issued at 155 AM CST Sun Feb 5 2023
Through Monday…
Primary forecast concerns include fog potential early Monday morning and gusty southeast winds Monday afternoon.
Southwest winds still gusting into the 30 mph range at times early this morning and these gusts will diminish some by daybreak as directions slowly turn more westerly later this morning and then northwest this afternoon. Gusts into the 25 mph range will remain possible through mid/late afternoon. High pressure will move across the area tonight with winds becoming light and variable or calm overnight and will then shift southeasterly Monday morning. The gradient will take some time to tighten Monday, but by mid/ late afternoon, gusts into the 30 mph will be possible.
Confidence for cloud cover remains fairly low through tonight. Guidance has backed away from lower ceilings developing this morning but there may still be some lower clouds today. But if they don`t develop, then today could end up being mostly sunny.
There is a chance for some fog to develop late tonight into Monday morning, mainly west and south of the Chicago metro area. Current placement of patchy fog seems reasonable, though it could extend further east across the far southern cwa.
High temps today and again on Monday may remain in the 30s for areas across far northern IL that maintain a snow pack and confidence is low for high temps for these areas. Better chance for highs in the lower or mid 40s will be along/south of I-80.
